PLS HELP!!!The mayor wants to know if her city's residents will support a tax increase to build a new library. Which method of sampling would produce the least biased results?

step-by-step explanation:

just plug in each number for x and see which ones work and don't

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

5/12, or 5: 12

step-by-step explanation:

r and t.

both are 64 degrees.
